BACKGROUND OF THE INVENTION

[0002] This invention relates to N-(4-sulfonylaryl)cyclylamine2-hydroxyethylamine derivatives which are β₃ adrenergic receptoragonists useful for the treatment of metabolic disorders related toinsulin resistance or hyperglycemia (typically associated with obesityor glucose intolerance), atherosclerosis, gastrointestinal disorders,neurogenetic inflammation, glaucoma, ocular hypertension, and andfrequent urination, and are particularly useful in the treatment orinhibition of type II diabetes.

[0003] The subdivision of β adrenergic receptors (β-AR) into β₁- andβ₂-AR has led to the development of β₁- and β₂-antagonists and/oragonists which have been useful for the treatment of cardiovasculardisease and asthma. The recent discovery of “atypical” receptors, latercalled β₃-AR, has led to the development of β₃-AR agnoists which may bepotentially useful as antiobesity and antidiabetic agents. For recentreviews on β₃-AR agnoists , see: 1. A. D. Strosberg, Annu. Rev.Pharmacol. Toxicol. 1997, 37, 421; 2. A. E. Weber, Ann. Rep. Med. Chem.1998, 33, 193; 3. C. P. Kordik and A. B. Reitz, J. Med. Chem. 1999, 42,181; 4. C. Weyer, J. F. Gautier and E. Danforth, Diabetes andMetabolism, 1999, 25, 11.

[0004] Compounds that are potent and selective β₃ agonists, may bepotentially useful antiobesity agents. Low levels or lack of β₁ andβ₂-agonistic properties will minimize or eliminate the adverse sideeffects that are associated with β₁ and β₂ agonistic activities, i.e.increased heart rate, and muscle tremor, respectively.

[0005] Early developments in the β₃-agonist field are described inEuropean patent 427480, U.S. Pat. Nos. 4,396,627, 4,478,849, 4,999,377,5,153,210. Although the early developments purport to claim compoundswith greater β₃-AR selectivity over the β₁- and β₂-AR. However, clinicaltrials in humans with those early developed β₃-agonists have, so far,not been successful.

[0006] More recently, potent and selective human β₃ agonists have beendescribed in several patents and published applications: WO 98/32753, WO97/46556, WO 97/37646, WO 97/15549, WO 97/25311, WO 96/16938, WO95/29159, European Patents 659737, 801060, 714883, 764640, 827746, andU.S. Pat. Nos. 5,561,142, 5,705,515, 5,436,257, and 5,578,620. Thesecompounds were evaluated in Chinese hamster ovary (CHO) cells testprocedures, expressing cloned human β₃ receptors, which predict theeffects that can be expected in humans (Granneman et al., MolPharmacol., 1992, 42, 964; Emorine et al., Science, 1989, 245, 1118;Liggett Mol. Pharmacol., 1992, 42, 634).

[0007] β₃-Adrenergic agonists also are useful in controlling thefrequent urge of urination. It has been known that relaxation of thebladder detrusor is under beta adrenergic control (Li J H, Yasay G D andKau S T Pharmacology 1992; 44: 13-18). Beta-adrenoceptor subtypes are inthe detrusor of guinea-pig urinary bladder. Recently, a number oflaboratories have provided experimental evidence of β₃ adrenergicreceptors in a number of animal species including human (Yamazaki Y,Takeda H, Akahane M, Igawa Y, et al. Br. J. Pharmacol. 1998; 124:593-599), and that activation of the β₃ receptor subtype bynorepinephrine is responsible for relaxation of the urinary bladder.

[0008] Urge urinary incontinence is characterized by abnormalspontaneous bladder contractions that can be unrelated to bladder urinevolume. Urge urinary incontinence is often referred to hyperactive orunstable bladder. Several etiologies exist and fall into two majorcategories, myogenic and neurogenic. The myogenic bladder is usuallyassociated with detrusor hypertrophy secondary to bladder outletobstruction, or with chronic urinary tract infection. Neurogenicbladders are associated with an uninhibited micturition reflex. An uppermotor neuron disease is usually the underlying cause. In either case,the disease is characterized my abnormal spontaneous contractions thatresult in an abnormal sense of urinary urgency and involuntary urineloss. At present, the most common therapy for hyperactive bladderincludes the use of antimuscarinic agents to block the action of theexcitatory neurotransmitter acetylcholine. While effective in neurogenicbladders, their utility in myogenic bladders is questionable. Inaddition, due to severe dry mouth side-effects associated withantimuscarinic therapy, the patient compliance with these agents is onlyapproximately 30%.

[0009] In the bladder, β₃ adrenergic receptor agonists activate adenylylcyclase and generate cAMP through the G-protein coupled β₃ receptor. Theresulting phosphorylation of phospholamban/calcium ATPase enhancesuptake of calcium into the sarcoplasmic reticulum. The decrease inintracellular calcium inhibits bladder smooth muscle contractility.

[0010] It is suggested therefore, that activation of the β₃ adrenergicreceptor in the urinary bladder will inhibit abnormal spontaneousbladder contractions and be useful for the treatment of bladderhyperactivity. Note, that unlike the antimuscarinics, β₃ adrenergicreceptor agonists would be expected to be active against both neurogenicand myogenic etiologies.

[0011] Despite all these recent developments there is still no singletherapy available for the treatment of type II diabetes (NIDDM),obesity, atherosclerosis, gastrointestinal disorders, neurogeneticinflammation, frequent urination and related diseases. A potent andselective β₃ adrenergic receptor agonist is therefore highly desirablefor the potential treatment of such disease states.

[0119] The compounds of this invention were be prepared according to thefollowing schemes from commercially available starting materials orstarting materials which can be prepared using literature procedures.These schemes show the preparation of representative compounds of thisinvention.

[0120] In general, as shown in Scheme 1, compounds of the presentinvention are prepared by reductive amination ofN-(4-sulfonylaryl)-substituted oxo-cyclylamines with the appropriatearyl-substituted ethanolamines. Various oxo-cycylamine derivatives canbe prepared according to one of the synthetic Schemes 2 to 7.

[0121] Many of the aryloxypropanolamines and arylethanolamines used inScheme 1 are commerically available or readily prepared by known methods[e.g., 1. A. Guy, Synthesis, 1992, 821; 2. A. A. Asselin, J. Med. Chem.,1986, 1009; 3. M. S. Berridge et al., Nucl. Med. Biol., 19, 1992, 563;4. C. D. Jesudason, et al., EP0764640; 5. EP0659737.]. In one method(Scheme 8), equimolar amounts of a substituted phenol and (2S) or(2R)-glycidyl 3-nitrobenzenesulfonate are dissolved in an organicsolvent such as acetone or dimethylformamide and treated with a basesuch as sodium hydride or potassium carbonate for 0.5 to 24 hours attemperatures of 20 to 100° C. to provide the correspondingaryloxyoxiranes. The aryloxyoxiranes are converted to the ethanolaminesby regioselective ring opening of the oxirane with lithium azide in asolvent such as hexamethylphosphoramide, followed by reduction withtriphenylphosphine or hydrogenation with 10% Pd/C as catalyst.Alternatively, the aryloxyoxiranes can be converted to the ethanolaminesby regioselective ring opening of the oxirane with dibenzylamine,followed by hydrogenation with 10% Pd/C as catalyst.

[0122] The arylethanolamines used in Scheme 1 can be prepared accordingto the methods shown in Scheme 9. Arylmethylketones are converted to thecorresponding α-haloketones using known methods [J. March, AdvancedOrganic Chemistry, 3rd Ed., John Wiley and Sons, New York: 1985, p529and references cited therein]. The haloketones are reduced to thecorresponding alcohol which can be protected as the triethylsilyl ether,or converted directly to the ethanolamine by treatment with ammonia orsodium azide followed by reduction. Treatment of the halo silyl etherwith benzylamine followed by desilylation and hydrogenation also givesthe corresponding arylethanolamine.

[0123] The compounds of this invention are useful in treating metabolicdisorders related to insulin resistance or hyperglycemia, typicallyassociated with obesity or glucose intolerance. The compounds of thisinvention are therefore, particularly useful in the treatment orinhibition of type II diabetes. The compounds of this invention are alsouseful in modulating glucose levels in disorders such as type Idiabetes.

[0124] The ability of compounds of this invention to treat or inhibitdisorders related to insulin resistance or hyperglycemia was establishedwith representative compounds of this invention in the followingstandard pharmacological test procedures, which measured the bindingselectivity to the β₁, β₂ and β₃ adrenergic receptors. Binding to thereceptors was measured in Chinese Hamster ovary (CHO) cells that weretransfected with adrenergic receptors. The following briefly summarizesthe procedures used and results obtained.

[0125] Transfection of CHO cells with β₁ and β₂ adrenergic receptors:CHO cells were transfected with human β₁- or β₂-adrenergic receptors asdescribed in Tate, K. M, Eur. J. Biochem., 196:357-361 (1991).

[0126] Cloning of Human β₃-AR Genomic DNA: cDNA was constructed byligating four polymerase chain reaction (PCR) products using thefollowing primers: an ATG-Narl fragment, sense primer5′-CTTCCCTACCGCCCCACGCGCGATC3′ and anti-sense primer5′CTGGCGCCCAACGGCCAGTGGCCAGTC3′; a Narl-Accl fragment,5′TTGGCGCTGATGGCCACTGGCCGTTTG3′ as sense and5′GCGCGTAGACGAAGAGCATCACGAG3′ as anti-sense primer; an Accli-Stylfragment, sense primer 5′CTCGTGATGCTCTTCGTCTCACGCGC3′ and anti-senseprimer 5′GTGAAGGTGCCCATGATGAGACCCAAGG3′ and a Styl-TAG fragment, withsense primer 5′CCCTGTGCACCTTGGGTCTCATCATGG3′ and anti-sense primer5′CCTCTGCCCCGGTTACCTACCC3′. The corresponding primer sequences aredescribed in Mantzoros, C. S., et.al., Diabetes 45: 909-914 (1996). Thefour fragments are ligated into a pUC 18 plasmid (Gibco-BRL) andsequenced. Full length β₃ AR clones (402 amino acids) containing thelast 6 amino acids of hβ₃ _(—) AR are prepared with the β₃-βARpcDNA3from ATTC.

[0127] Binding Procedure: Clones expressing receptor levels of 70 to 110fmoles/mg protein were used in the test procedures. CHO cells were grownin 24-well tissue culture plates in Dulbecco's Modified Eagle Media with10% fetal bovine serum, MEM non-essential amino acids,Penicillin-Streptompycin and Geneticin. On the day of test procedure,growth medium was replaced with preincubation media (Dulbecco's ModifiedEagle Media and incubated for 30 minutes at 37° C. Preincubation mediumwas replaced with 0.2 ml treatment medium containing DMEM mediacontaining 250 μM IBMX (isobutyl-1-methylxantine) plus 1 mM ascorbicacid with test compound dissolved in DMSO. Test compounds were testedover a concentration range of 10⁻⁹ M to 10⁻⁵ M for β₃ cells and 10⁻⁸ to10⁻⁴ M for β₁ and β₂ transfected cells. Isoproterenol (10⁻⁵ M) was usedas an internal standard for comparison of activity. Cells were incubatedat 37° C. on a rocker for 30 min with the β₃ cells and 15 min for β₁ andβ₂ cells. Incubation was stopped with the addition of 0.2N HCl andneutralized with 2.5N NaOH. The plates, containing the cells andneutralized media, were stored at −20 degrees celsius until ready totest for cAMP using the SPA test kit (Amersham).

[0128] Data Analysis and Results: Data collected from the SPA testprocedure were analyzed as per cent of the maximal isoproterenolresponse at 10⁻⁵ M. Activity curves were plotted using the SASstatistical and graphics software. EC₅₀ values were generated for eachcompound and the maximal response (IA) developed for each compound iscompared to the maximal response of isoproternol at 10⁻⁵ M from thefollowing formula:

IA=% activity compound/% activity isoproterenol

[0136] The compounds of this invention may also be administeredparenterally or intraperitoneally. Solutions or suspensions of theseactive compounds as a free base or pharmacologically acceptable salt canbe prepared in water suitably mixed with a surfactant such ashydroxy-propylcellulose. Dispersions can also be prepared in glycerol,liquid polyethylene glycols and mixtures thereof in oils. Under ordinaryconditions of storage and use, these preparation contain a preservativeto prevent the growth of microorganisms.

[0137] The pharmaceutical forms suitable for injectable use includesterile aqueous solutions or dispersions and sterile powders for theextemporaneous preparation of sterile injectable solutions ordispersions. In all cases, the form must be sterile and must be fluid tothe extent that easy syringability exists. It must be stable under theconditions of manufacture and storage and must be preserved against thecontaminating action of microorganisms such as bacteria and fungi. Thecarrier can be a solvent or dispersion medium containing, for example,water, ethanol, polyol (e.g., glycerol, propylene glycol and liquidpolyethylene glycol), suitable mixtures thereof, and vegetable oils.

[0138] Suppository formulations may be made from traditional materials,including cocoa butter, with or without the addition of waxes to alterthe suppository's melting point, and glycerin. Water soluble suppositorybases, such as polyethylene glycols of various molecular weights, mayalso be used.

[0139] The compounds of the present invention also possess utility forincreasing lean meat deposition and/or improving lean meat to fat ratioin edible animals, i.e. ungulate animals and poultry.

[0140] Animal feed compositions effective for increasing lean meatdeposition and for improving lean meat to fat ratio in poultry, swine,sheep, goats, and cattle are generally prepared by mixing the compoundsof the present invention with a sufficient amount of animal feed toprovide from about 1 to 1000 ppm of the compound in the feed. Animalfeed supplements can be prepared by admixing about 75% to 95% by weightof a compound of the present invention with about 5% to about 25% byweight of a suitable carrier or diluent. Carriers suitable for use tomake up the feed supplement compositions include the following: alfalfameal, soybean meal, cottonseed oil meal, linseed oil meal, sodiumchloride, cornmeal, cane molasses, urea, bone meal, corncob meal and thelike. The carrier promotes a uniform distribution of the activeingredients in the finished feed into which the supplement is blended.It thus performs an important function by ensuring proper distributionof the active ingredient throughout the feed. The supplement is used asa top dressing for the feed, it likewise helps to ensure uniformity ofdistribution of the active material across the top of the dressed feed.

[0141] The preferred medicated swine, cattle, sheep and goat feedgenerally contain from 0.01 to 400 grams of active ingredient per ton offeed, the optimum amount for these animals usually being about 50 to 300grams per ton of feed. The preferred poultry and domestic pet feedusually contain about 0.01 to 400 grams and preferably 10 to 400 gramsof active ingredient per ton of feed.

[0142] For parenteral administration the compounds of the presentinvention may be prepared in the form of a paste or a pellet andadministered as an implant, usually under the skin of the head or ear ofthe animal in which increase in lean meat deposition and improvement inlean mean to fat ratio is sought. In general, parenteral administrationinvolves injection of a sufficient amount of the compounds of thepresent invention to provide the animal with 0.001 to 100 mg/kg/day ofbody weight of the active ingredient. The preferred dosage for swine,cattle, sheep and goats is in the range of from 0.001 to 50 mg/kg/day ofbody weight of active ingredient; whereas, the preferred dose level forpoultry and domestic pets is usually in the range of from 0.001 to 35mg/kg/day of body weight.

[0143] Paste formulations can be prepared by dispersing the activecompounds in a pharmaceutically acceptable oil such as peanut oil,sesame oil, corn oil or the like. Pellets containing an effective amountof the compounds of the present invention can be prepared by admixingthe compounds of the present invention with a diluent such as carbowax,carnuba wax, and the like, and a lubricant, such as magnesium or calciumstearate, can be added to improve the pelleting process. It is, ofcourse, recognized that more than one pellet may be administered to ananimal to achieve the desired dose level which will provide the increasein lean meat deposition and improvement in lean meat to fat ratiodesired. Moreover, it has been found that implants may also be madeperiodically during the animal treatment period in order to maintain theproper drug level in the animal's body. For the poultry and swineraisers, using the method of the present invention yields leaneranimals.

[0144] Additionally, the compounds of this invention are useful inincreasing the lean mass to fat ratio in domestic pets, for the petowner or veterinarian who wishes to increase leanness and trim unwantedfat from pet animals, the present invention provides the means by whichthis can be accomplished.
